The Simple Cactus may have the answer the Clean Tech industry needs

In the world of engineering, you can usually trust nature to have done it first, and better. A newly-developed fuel cell technology looks to the cactus to solve a problem involving this promising but complex form of clean energy, which generates power without emitting planet-warming greenhouse gases.

The technology, which is a thin plastic membrane, could help improve the performance of fuel cells to make them more useful for everything from electric cars to desalination plants.
